摘要： A shoe clearance over-adjustment prevention apparatus employable to various types of automatic shoe clearance adjustment devices and drum brakes and designable to have a common thermo-sensitive member suitable for mass production. The thermo-sensitive member 60 is sandwiched between the strut 20 and the brake lever 30 to cause a functional engagement, and if the brake temperature reaches a predetermined value or range, the strut 20 is pushed toward the brake shoe 12 so as to disable the automatic shoe clearance adjustment operation.

摘要： A adjustment lever (80) has dual-functions characterized in that when an actuating force to a brake shoe (20) to move outward reaches predetermined magnitude, a device (80g) prevents over-adjustment of shoe-to-drum clearances disables a device (70) to restrict return positions of brake shoes inhibiting the brake shoes movement in the direction to separate each other and when a brake temperature rises certain degree, a device (80d) to prevent over-adjustment of brake shoe-to-drum clearances disables the device (70) to restrict return position inhibiting the brake shoe movement as well. The inventive design secures the function of over-adjustment prevention of the shoe-to-drum clearances and to downsize and to lighten a drum brake device without sacrificing its operation

摘要： A brake cable connecting apparatus having a cable end insertion groove 120a formed by U-like folding the free end of a brake lever 120 on one of brake shoes 1, 2 and a guiding member 150 provided onto the cable end insertion groove 120a. The guiding member 150 tends to move toward the bottom of the insertion groove 120a by a coil spring 160. When the cable end 142 is advanced in the insertion groove 120a, the guiding member 150 moves upward, passage of the cable end 142 is permitted by displacement of the guiding member 150 in a direction away from the bottom of the insertion groove 120a, then the guiding member 150 immediately moves downward, thereby engaging a backward surface of the cable end 142; therefore, restricting the cable end 142 from coming off.

摘要： A brake structure that prevents damaging the shoe-hold mechanism by way of securing a larger space at a central region of the brake and achieves a long effective and stable brake function. A by-pass hole 60d, through which the shoe-hold pin 41 is freely penetrating, is formed in the brake lever 60 positioned beneath the shoe web 20b of the brake shoe 20, and the stopper portion 60e contacting the shoe rim 20a is formed on the brake lever 60 so as to avoid the collision between the shoe-hold pin 41 and the by-pass hole 60d when the brake lever 60 is in operation.

摘要： It is an object of this invention to provide an automatic shoe clearance adjustment device for a drum brake mechanism designed to improve its durability by eliminating a gap, which is caused due to the manufacturing tolerances between the operating end surface of a brake shoe and the extended portion of an adjustment lever. To that end, a long hole (81) is formed to extend horizontally in the actuating direction of a service brake actuator (50); and the adjustment lever (80) is pivotally supported via a pin (14) with a capacity of making a rotation relative to the brake shoe (20) and a capacity of making a relative slide in approximately the same direction in which the service brake actuator (50) operates.

摘要： A device for detachably connecting an end fitting of a control cable with a control lever in an operating device is composed in such manner that it makes the operating device to be more short and workability of cable connection to be enhanced. The operating device consists of a strut and a control lever which are pivotally journalled to each other. A end fitting of a control cable is engaged with a free end of the control lever, which free end is bifurcated by means of planar members spaced from each other so as to define a gap. In order to engage the end fitting with the free end of the control lever, the end fitting is set so that its long side is parallel with the planar members and then passed through the gap. Thereafter, the end fitting is rotated around the cable axis by an angle of 90 deg. and the cable is pulled to engage with the free end of the control lever.

摘要： A drum brake device that functions as a leading-trailing (LT) type when the service brake is applied, and as a duo-servo (DS) type when the parking brake is applied, in which the automatic shoe clearance adjustment mechanism functions precisely for a prolonged period, thereby generating no strange noise. This mechanism also eliminate any impact load applied to any of the components, thus enabling a lighter device. The middle segment of a long link 11 is pivotable in the middle of the one brake shoe 2.
